Optimization car travel problem

  1. Apr 2, 2009 #1
    I have been working on this problem for 30 min and can;t seem to get anywhere.


    Question

    You have a amphibian vehicle which can travel 20 mph on the water and 52 mph on the land. You must find the quickest point from point A to C.

    -A is 20 Miles east of point B and is all land.
    -C is 12 miles north of point B and is all water.

    -Calculate the minimum time.



    My thinking

    At the moment i can only think so find where the area of the triangle has minimum area. Because traveling in water is hurts the time when going on land is 2.6 times faster.

    If anyone has any ideas to this problem that be great. Ill keep working on it.
